Hello
I'm currently using the 6x8_series_pinout_tracelength excel file to adjust lines on our PCB Carrier board hosting the TEI0006 SOM.
The Excel proposes only TEI0006 Rev3 trace lengths. Do you provide also the TEI0006 Rev4 trace lengths ? Maybe there no trace lengths differences between rev 3 and rev 4 ?
Best regards
There usually are no differences between hardware revisions

But it safer to use the trace length that matches the PCB revision, for the rare case that the lenght have been changed.

I did manual inspecition of all routing layers, and do my eye there has been no change on any differential pair routing between rev 03 and rev 04. We should still update our trace length info to be on the safe side.
